IPC: B23P11/00
Filed: 1961-11-03
Abstract: 955,179. Assembling resilient bushes. J. & S. ENGINEERS Ltd. Oct. 29, 1962 [Nov. 3, 1961; May 23, 1962; Sept. 10, 1962], Nos. 39412/61, 19830/62 and 34512/62. Heading F2S. [Also in Division B3] A method of providing a composite insert e.g. a lead through conductor assembly in a previously imperforate sheet of material, one of the insert components being of a softer material than that of the sheet comprises placing the sheet between a ram and die of a press, retaining the separate insert components between the ram and the sheet so that said components are successively aligned with the die and each other, moving the ram and die together to force said components together to constitute the composite insert, shrouding the space between the ram and the sheet to enclose at least said one component of the insert and to restrict cold flow of the material thereof and continuing said movement of the ram and die to force the softer material portion of the insert into the sheet while a part of the sheet is sheared out into the die. A ridged or grooved metal pin 2 inserted in a ram bore 12 is forced into a cylindrical billet 10 e.g. nylon, aluminium or soft brass contained within a shroud 8, positioned above a sheet e.g. metal or synthetic resin bonded plastic (S.R.B.P.) board which is itself positioned over a die 5 having a square or circular aperture. The pin initially pierces the sheet whilst continued downward movement of the ram compresses the billet, the upper face of which is shaped by a ram recess 11 until the hydrostatic pressure exerted by the billet shears a piece of material from the sheet allowing the leading end of the billet to pass through the aperture so produced and expand thereby keying itself to the sheet. The ram is withdrawn and the die expanded to permit removal of the assembled insert. The upper portion of the insert bush 3 is circular whilst the lower portion is circular or rectangular. In a first modification a rigid insert plate 16 positioned in an annular plastic ring 17 is similarly inserted in a sheet 18 until the plate lies in the plane of the sheet. A recess 24 of a ram 23 cold forms the ring over the plate. In a second modification a taper ended screw 28 and a plastic slug having a bore diameter less than the minor diameter of the screw is similarly assembled in a sheet, the screw which is subsequently removed serving to form a screw thread in the slug. The tapered bore produced in the slug acts as a locking portion for retaining screws which are subsequently screwed through the insert. To produce more controlled locking the leading end of the insert may have slots formed therein. Specification 931,875 is referred to.

Filed: 1967-09-01
Abstract: 1,203,787. Position indicating scales; photoelectric measurement systems. J. HEIDENHAIN [trading as WENCZLER & HEIDENHAIN]. Sept. 1, 1967 [Sept. 1, 1966], No. 40146/67. Headings G1A and G1J. A scale for use in determining the position of an object such as the work table of a machine tool comprises n graduation members a 6- i6 the centroids of which are spaced in accordance with a periodically repeated pattern and at integral numbers of a standard unit distance from each other, the pattern having a length of P units where P= n(n-1)/k + 1, k being an integer, and the pattern being such that for each integer x from 1 to n(n-1)/k,the centroids of k graduation members of any one pattern are spaced from the centroids of other graduation members of the same pattern or of one adjacent pattern by x units. Fig. 6 illustrates schematically the construction of a scale consisting of nine graduation members in the form of transparent windows and for which k=4. Thus the integers x equals 1 to 18 are each represented four times by the distance between the centroids of pairs of the windows. A scale constructed in accordance with a pattern complementary to that shown in Fig. 6, that is a scale having opaque portions where the pattern of Fig. 6 has windows, is illustrated in Fig.10 and consists of a number of repetitions of the pattern plus a number of blank portions. When a pair of such scales 100, 101 are moved relatively to each other and illuminated by a lamp 103 the light transmitted through the scales undergoes a steeper variation in intensity in the region of the position in which the windows in the two scales coincide than in any other relative positions. A photo-converter 106 provides an electrical signal in its output lead 107. (For Figures see next page)

Abstract: 1339596 Hoists C H ARNOLD 3 Sept 1971 [4 Sept 1970] 41111/71 Headings B8B and B8M A hoisting device comprises a drum 10 provided with a plurality of peripheral grooves in planes at right angles to the drum axis, a hoisting rope 18, 19 wound with a plurality of parallel windings on the drum and a plurality of transfer rollers 21-26 spaced around the periphery of the drum for deflecting the rope from one groove to the adjacent groove, tension rollers 43-50 being provided interspaced with the deflecting rollers to press the rope into the drum grooves. The tensioned end 18 of the rope up which the hoist climbs, passes around the drum for 300 degrees whereat it is shunted by the roller 21 into the adjacent groove for a further 300 degrees and so on until the slack end 19 of the rope passes from the hoist, the rope being guided to and from the drum by guides 85 and 73 which together with the transfer and tension rollers facilitate self reeving of the cable on the hoist. Each transfer roller has a contoured surface to accept the rope windings on the drum except in the area of the two particular drum grooves between which the rope is to be transferred where an enlarged flange on the roller engages the rope for transference, the roller being angled to facilitate the transfer. Flanges on the drum 10 restrict axial shift of the rollers. The tension rollers which are spring biased towards the drum 10 are contoured to accept the rope windings and are frictionally driven by the drum flanges. The drum 10 which is driven through worm gearing 3 and 4 may be provided with plastics inserts for recesses in the roots of the grooves and the groove diameters may be graduated across the drum. In the modification of Fig. 10 (not shown) the rope is guided on to the drum through a housing having a stepped enlarged bore whereby excessive inherent curl in the rope end catches on the step and is prevented from entry to the hoist for reeving. In the embodiment of Fig. 9 (not shown) the hoist is secured to stationary structure and each of the rope extends to support a load, cage or counterweight. In a modification, Figs. 11, 12, 13 (not shown) all the transfer rollers are positioned over the half of the diameter of the drum to and from which the rope extends and the rollers are associated with a pair of cables connected to either a safety cut out for the hoist motor or a rope grip brake, whereby faulty hoist cable passing beneath the rollers will cause a stoppage of the hoist.
